حلقات قفل خارجية بأسنان M4 | فولاذ مطلي بالزنك (3000 / عبوة)

Exactly what I needed for securing a few vibration-prone M4 fasteners on my motorcycle. The zinc plating looks clean and consistent across all 3000 pieces, and they bite nicely under the bolt head. No complaints at all.

Needed a bulk lot for an automotive project, and these zinc-plated washers are holding up great against a bit of moisture. The 3000 count means I won't run out anytime soon, and each one fits perfectly on the M4 bolts. Exactly what you'd expect for the price.

Installed these on a few brackets that kept loosening from machine vibration, and they’ve held rock solid for two weeks now. The steel feels sturdy, and 3000 pieces in a bag is plenty for multiple projects.
